Can hamsters have tumors?

Question
I was looking at my hamster when I was feeding him a carrot i noticted that he had a big lump on his bottom half!!! What should i do!!


PS. He is a dwarf hamster!!!!

Answer
Hmmm... are you sure it's not his testicles on his behind? If you are not sure if it's his testicles dropping then take him to a vet. I really can't give you a direct answer so the best thing to do is to take your hamster to a vet to get looked at. sorry I can't be of more help to you but without know if there is fur on the lump or how big it is it's hard to give a diagnosis.
